IMPROVED ADJUSTABLE HANGER Fori SHAPTING.

The Schedulereferred to in these Letters Patent making part of the same To all whom it may concern :A

Be it known that I, VoLxEY W. MASON, of the cit-y and county 'of Providence, and State of Rhode Island, have invented a new and improved Hanger- Bearing for Shaftiug; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specification, iu which- Figure 1 is a plan view of the hanger longitudinally with the shaft, showing a drophanger terminating at the bottom with the concave surface receiving the ball bearing B, and convex surface receiving the retaining-cap C, which is held in its proper Apiace by the nuts E E.

Figure 2 is aview of the sameat a right angle to fig. 1, similar parts being indicatedby like letters.

Figure 3 is a. section through fig. 2, showing the internal construction of the bali bearing B, with the ring F, for purpose of mising the oil or liquid, in which itz-runs, to the top of thc shaft; also, the recesses at the ends of the bearing andI passages for returning the liquid to the central chamber, thereby causing a. constant supply or lubrication when the shaft revolves; also shows the hollow stem or bolt D, and retaining-cap O, screw on stem, and nuts E E.

Figure 4 is a section through one of the standards oi the hanger, showing the dimensions of plate and ribs, similar to ordinaryhangers.

To enable others skilled in the art vto constructand use my invention, I will proceed to describe its construction and operation.

`Iconstruct the parts o'i' the hanger offcast and wrought iron, usually, although in some cases other metals or materials may hc employed, the principle remaining the same.

. specified.

The spherical cavity at the bottom of the hanger is cored out in the casting nearly to the finished size; in some cases the coi-ing may be exact to the size by proper attention being paid to the molding, or by the use of an iron core, although the socket is nsually finished by use of a couuterboriug tool.

The ball bearing B may be cast to the sizcfor a tride larger, amifinished to fit the socket.

The stem or bolt D may be first iiuished, 'then laid in the mold and cast solid with thc ball bearing B, or maybe screwed into the bearing B, or cast solid, of the same metal as B.

The concave cap C is iliade, on its inner circle, to

correspond with theoutside or convex surface on which it rests, which is the segment of al circle, having its center in the center of the ball bearing B.

The socket receiving the ball bearing B has a hole in its center larger than the stem D, to allow sniiicient oscillating movement for adjustment.

The two nut-s E E are provided, one to check the. other, so that the 'cap C may freely adjust with the bearing to the shaft. In some cases onel single nut may be applied, and that screwed down rmly to the cap C, after the shaft hasfound its proper bearing.

The ring F is made of spring-steel, or other suitable metal.

l I cla-im- A hanger-bearing, B, when constructed :and relatively arranged with the stern D, capG, nuts E E, spherical socket S, as described, and for the purposes lvoLnmLr W. MASON.
